Mercury (Hg) contents in ten chemical fertilizers were determined, and the effect of calcium superphosphate (CSP) on the uptake and translocation of Hg in corn seedlings was investigated by pot experiments. CSP was applied at the levels of 0, 66.7, and 133.4 mg P2O5/kg to Hg-treated (2 mg/kg) and untreated soils. CSP had the highest Hg content (5.1 mg/kg), followed by the NPK compound fertilize...

Agricultural useful soils in many parts of India and the world are slightly contaminated by presence of heavy metal toxicity. Few as Cd, Cu, Zn, Ni, Co, Cr, Pb, and As. This because long-term use of phosphatic fertilizers, sewage sludge application, dust from smelters, industrial waste and bad watering practices in agricultural lands [13]. Toxics Link in India has been involved both at the glob...

in most aquatic ecosystems mercury accumulates more in the sediment than in water column. however, due to limited eco-toxicological data, it is difficult to predict the toxicity of these sediments. the present study evaluated the effects of inorganic mercury in spiked sediment on the survival, growth, and emergence of the midge chironomus riparius and compared the results to mercury concentrati...

The concentration of mercury (Hg) in eggs that causes reduced hatching success is regarded as a critical end point for Hg toxicity in birds. However, incorporating effects of in ovo mercury exposure on chick health and survival could improve risk assessment. We developed equations to predict Hg in eggs using Hg in chick down feathers, and vice versa, by assessing the relationship between Hg in ...

Our study was based on the recent increase in wastewater pollution and its deleterious effects to the marine ecosystem. Using numerical simulation (DESCAR3.2 software program), we investigated the orientation and quantification of trace metals in wastewater discharges from permanent and semi-permanent drain outfalls constructed along the Kuwait Coastline encompassing six Kuwait Governorates (GI...

BACKGROUNDS: Heavy metal toxicity has confirmed to be a critical threat to animals’ health. It has been proved that heavy metals can cause immunosuppression. Although, it is said that damage of immune function plays a contributing role in the increasing incidence of infectious diseases. The increasing use of rural habitats by jackals make them suitable to monitor the impact of anthropogenic on ...

Abstract Identifying the key parameters or components mainly contributing to acute toxicity of wastewater would be helpful quickly and conveniently reflect their biological toxicity. In this study, components/parameters 64 effluent samples collected from two factories producing konjac glass were analyzed. It was found that types wastewaters not effectively dealt with. Moreover, evaluated by bio...

Emerging nanotechnologies hold great promise for creating new means of detecting pollutants, cleaning polluted waste streams, and recovering materials before they become wastes, thereby protecting environmental quality. Studies focusing on the different advantages of nanoscience and nanotechnology abound in the literature, but less research effort seems to be directed toward studying the fate a...

Abstract Mercury (Hg) is a heavy metal that commonly found in waters and sediments. its derivatives are highly toxic ) . Their presence the aquatic environment can be very detrimental. Aspergillus fungi known to reduce Hg levels pollutants. Our research aim was evaluate effect of after being reduced by local isolates Penicillium sp. strain A4. A toxicity test conducted on juvenile Caroline plat...

Mercury (Hg) is neurotoxic and children may be particularly susceptible to this effect. A current major challenge is identification of children who may be uniquely susceptible to Hg toxicity because of genetic disposition. This study examined the hypothesis that genetic variants of catechol-O-methyltransferase (COMT) that are reported to alter neurobehavioral functions that are also affected by...
